As reported today by the CBC, City of Calgary Bylaw will soon "crack down" on cyclists exceeding the speed limit of 20 km/h (posted 10 km/h limits in certain areas). So it's perhaps time to remind everyone that almost all of Calgary's pathways are shared with other users. To be sure, those other users often do not follow the rules -- there are a lot of problems with people walking their dogs and not controlling them or letting them run off-leash, and runners using the bike-only parts of twinned pathways -- and the City should also address these issues. Nevertheless, cyclists have the responsibility to be courteous and safe when using the pathways. Ride at a safe speed, signal, announce your approach, yield to the right, and light up at night.
Bike Calgary's position has always been that Calgary's pathways are excellent for recreational cycling but (with exceptions) when shared with pedestrians are not perfectly appropriate commuter infrastructure especially because of the speed differential between cyclists and other pathway users. Consequently, Bike Calgary has in the past opposed raising the speed limit on shared pathways. The only solution, of course, would be to provide efficient, safe, direct, and dedicated infrastructure (on and off street) for commuter cyclists to ride at speeds above 20 km/h.
